166177600 | VIBRATOR | 9 |
20100139912 | Drill String Suspension - Vertical and/or directional drilling apparatus where compliant support air bag, magnetic or the like) is provided for a vibrational head and drive assembly that carries the drill string. With the vibrational head having a shuttle from which vibration is not directly taken and with the compliant support allowing pull back in the directional mode several advantages arise. | 06-10-2010 |
20120160476 | VIBRATION TOOL - A downhole vibration tool for connection with a pipe string, including a housing, a sleeve contained within the housing, a sleeve bore defined by the sleeve, an annular bore defined between the sleeve and the housing, an unbalanced annular turbine rotatably contained within the annular bore, an inlet for introducing a fluid into the sleeve bore and the annular bore, and an outlet for discharging the fluid from the sleeve bore and the annular bore. | 06-28-2012 |
20130043021 | Subterranean Vibrator with Lateral Vibration Feature - A vibratory tool for use in a tubular string to prevent sticking or to release a stuck string features a fluid operated dart valve working in conjunction with an impact sleeve to deliver continuous axial jarring blows in opposed directions as long as flow is maintained. Movement of one of those components axially in opposed directions opens and closes access to opposed lateral ports so that a lateral vibration is also established as flow cyclically occurs and stops sequentially at opposed lateral outlets. | 02-21-2013 |
20130160991 | Propulsion Generator and Method - A propulsion generator which employs one or more unbalanced rotors, such as a fly wheels or other unbalance rotating members, which can be connected at a lower portion of a downhole coiled tubing string or other downhole tubular string for inducing propulsion of the coiled tubing. The unbalanced rotors may, in one embodiment, be oriented at different positions with respect to each other. The instantaneous fluid flow through the propulsion generator is substantially equivalent to the average fluid flow rate through the tool to provide relatively consistent fluid flow to downhole motors below the propulsion generator for operating the drill bit and/or cutters. | 06-27-2013 |
20130168080 | RADIAL VIBRATIONAL APPARATUS - A downhole assembly able to generate a vibrational output reliant upon a fluid feed drive to cause relative rotation extending magnetic arrays and thereby a relative longitudinal vibration causing reciprocation. | 07-04-2013 |
20130306305 | VIBRATION TOOL - A downhole vibration tool for connection with a pipe string, including a housing, an unbalanced turbine assembly contained within the housing, an inlet for introducing a fluid into the unbalanced turbine assembly, and an outlet for discharging the fluid from the unbalanced turbine assembly. The unbalanced turbine assembly includes a sleeve and at least one annular turbine which is located in an annular bore defined between the housing and the sleeve. | 11-21-2013 |
20160017694 | PROPULSION GENERATOR AND METHOD - A propulsion generator which employs one or more unbalanced rotors, such as a fly wheels or other unbalance rotating members, which can be connected at a lower portion of a downhole coiled tubing string or other downhole tubular string for inducing propulsion of the coiled tubing. The unbalanced rotors may, in one embodiment, be oriented at different positions with respect to each other. The instantaneous fluid flow through the propulsion generator is substantially equivalent to the average fluid flow rate through the tool to provide relatively consistent fluid flow to downhole motors below the propulsion generator for operating the drill bit and/or cutters. | 01-21-2016 |
20160040497 | VIBRATION TOOL - A downhole vibration tool for connection with a pipe string, including a housing, an unbalanced turbine assembly contained within the housing, an inlet for introducing a fluid into the unbalanced turbine assembly, and an outlet for discharging the fluid from the unbalanced turbine assembly. The unbalanced turbine assembly includes a sleeve and at least one annular turbine which is located in an annular bore defined between the housing and the sleeve. | 02-11-2016 |
